The effect of aluminum additives on the microstructure of bainitic malleable cast iron after heat treatment consisting of isothermal hardening at 350°C in a bath with molten lead after a hold at 920°C for 90 min is studied. ...

The presence of well distributed graphite in the matrix, and a relatively high volume fraction of retained austenite, are responsible for the good mechanical properties of the austempered ductile irons including excellent ...

The oxidation resistance of ductile irons alloyed with aluminium in the range from 0.08 to 6.16 wt.% has been investigated by heating at 550°C for periods up to 1270 h. Examination by light and SEM microscopy and EPMA ...

الگوی ریزجدایش عناصر آلیاژی آلومینیوم و سیلیسیم در چدن ها با گرافیت کروی تحقیق شده است. تجزیه های میکروسکوپی توسط EDX و EPMA بیانگراین واقعیت است که در زمینه چدن های ریختگی آزمایش شده نایکنواختی وجود دارد. در نواحی نزدیک ...

The temperature for the start of martensite formation (MS) for three Al-alloyed ductile irons containing 0.48%Al, 4.88%Al and 6.16%Al were determined by high-speed dilatatometry. Microscopic observation also were used to ...

The influence of aluminium, within the range of 0.08 - 6.16 wt.%, on the microstructure and hardness of as-cast ductile cast iron have been studied. A number of irons of different composition have been made by green sand ...
